If it was signed in his early years then it could be real. Jordan used to sign more like this with the bigger loops. You'd think if he was going to fake an auto it would be on a nice ball instead of a really old used rubber one that you use on the playground.

Don't even bother wasting your time/efforts looking at anything else. If you're buying to keep, then invest the extra $$$ and get UDA cert. If you're buying to flip ... find something else, because 99.99999999% of items like this are FAKE (not just Jordan, many other athletes/celebrities/etc)
